* a speci lication.

My invention relates to improvements in talking machines, the object of the invention being to provide an improved construction of talking machine which may be used in connection with various styles of records, and provide improved means whereby the sound box may be located at either of two positions relatively to the tone arm.

A further object is to provide improved means for supporting the stylus at any angle desired, whereby the tone may be softened or increased as desired.

A further object is to providean improved construction .of sound box having openings therein, and capable of adjustment relatively to the tone arm to position the stylus at the angle desired.

' A further object is to provide an improved construction of stylus bar adapted to support a needle at various angles and positions employing a singleset screw to secure the stylus in any of its operating positions.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a view in longitudinal section through my improved tone arm. Fig. 2 is a fragmentary view on an enlarged scale partly in plan and partly in section through the free ends of the tone arm. F ig. 3 is a view in section on the line 3-3 of Fig. 2. Fig. 4 is a view in elevation of the outer face of the Sound box. Fig. 5 is a similar view of the inner face of the sound box. Fig. 6 is a view in section through the centerof the sound box taken on the line 66 of Fig. 4. Fig. 7 is an enlarged view in section through the lower portion of the stylus bar, and Fig. 8'

is a View in section on the line 8-8 of Fig. 7

1 represents my improved tone arm hav ing a semi-spherical enlargement 2 at its larger end connected by a coupling ring 3 with a stationary ring 4, so that the tone arm 1 is permitted a rotary movement, and also a pivotal or vibrating movement to readily conform to the variations in the record groove.

I have not attempted to illustrate any par ticular form of talking machine, as I would have it understood that my improvements are adapted for any type of machine, and hence the reference numeral 5 indicates a support which may constitute the ordinary box, and 6 is arotary record disk such as commdnly el11])lO \'0(l,iI1 talking machines.

The free end of the tone arm 1 is provided with a lateral tubular extension 7 and a cylindrical slide 8 fits the extension and is provided with a closed inner end 9 adapted to close communication between the extension and the tone arm when said slide is in itsout-ward position shown in Fig. 2.

The slide 8 is open at its outer end. and is provided with an opening 10 in its side adjacent its inner end, so that when the slide is in its inner position, it serves to cut off the open end 11 of the tone arm and open communication between the extension 7 and the tone arm for a purpose which will hereinafter appear.

12 represents a button which is secured to the slide 8, and is movable in a slot 13, and the tone al'm adjacent its open end 11, is provided with a recess 14 to accommodate the end9 of slide 8 when the latter is in its inward position.

-15 represents my improved sound box which is relatively thin, and which is provided with a metal diaphragm 16 secured between packing, rings 17.

.18 is a nipple projecting centrally from the rear wall 20 of the sound box, and adapted to be positioned either in the opening 11 in the end of tone arm 1, or in the open end of the extension 7 as will be hereinafter explained. To provide a tight frictioned juncture between the nipple and the tone arm, I locate a gasket 21 around the nipple.

22 represents a stylus bar connected to the center of diaphragm 16, and adjacent its lower end pivotally connected by a pin 23 with a bracket 24 fixed to the bottom of the sound box. The extreme lower end of the stylus bar is provided with a plurality of recesses 25. Certain of these recesses are at an angle, while one of the recesses is vertically positioned, and a single set screw 26 is located in the stylus bar, and is adapted to extend across all of the said recesses 27 represents an ordinary needle or stylus which may be positioned in any of the recesses 25, and secured in any of them by the set screw 26; This plurality of recesses enables the stylus to be located either vertically or at any particular angle relatively to the sound box, and to the record disk.

I have found that by changing the angle of the stylus, variations may be had in the tone and in order to provide a wide range of such angular adjustment, I so firmly couple the nipple 18 in the tone arm-1 or extension 7 thereof that the sound box can be turned in either direction, and thereby vary the angle of the stylus. This can be readily understood by reference to Fig. 4, in which it will be noted that by turning the sound box, the angular disposition of the stylus can be varied. I have also discovered that with a sound box such as I have illustrated, improvement in the tone may be had by providing relatively small openings 28 in the rear wall 20 of the box.

With certain types of machines and records therefore, it is desirable to have the sound box parallel to the tone arm. With such machines the sound box will be' positioned in the extension 7 the slide 8 being located in its innermost position, cutting off the open end 11 of the tone arm. lVith other machines and records, it is desirable to have the sound box at the end of the tone arm in which position the box will be at right angles to the tone arm. Under such conditions, the nipple 18 Will be located in the opening 11 of the tone arm, and the slide 8 will be in its outward position as shown in Fig. 2.

It will therefore be noted that with my improved construction, the parts can be arranged in accordance with various kinds of records, and hence my improved machine is available for use in connection with almost any kind of record which can be purchased on the market.

Various slight changes might be made in the general form and arrangement of parts described Without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall Within the spirit and scope of the appended claims.

Having thus described my invention, Wh at I claim as new and desire to secure by Letters Patent is: r

1. The combination with a tone arm having an opening at one end, an extension projecting at an angle thereto, a slide in the extension adapted to out off either the extension or the open end of the tone arm, and a sound box adapted to'be supported in the extension or the end of the tone arm, substantially as described.

2. The combination with a tone arm having an opening at one end, an extension projecting at an angle thereto, a slide in the extension adapted to cut off either the extension or the open end of the tonearm, a

sound box adapted to be supported in the extension or the end of the tone arm, and said sound box having rotary adjustment in either of its positions, substantially as described.

3. The combination with a tone arm having a lateral extension adjacent its'open end, a hollow slide mounted in the extension having a closed inner end and an open outer end, said slide having an opening in its side adjacent its closed inner end, said extension having a longitudinalslot therein, and a button secured to the slide and projecting through the slot, substantially as described.

4. The combination with a tone arm having a lateral extension adjacent its open end, a hollow slide mounted in the extension having a closed inner end and an open 'outer end, said slide having an opening in its side adjacent its closed inner end, said extension having a longitudinal slot therein, a button secured to the slide and projecting through the slot, a sound box, and a nipple on the sound box constructed to fit the end of the extension and the end of the tone arm, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
